Abstract
Disclosed are a pixel compensation circuit, a method for driving the same, an organic light-emitting diode display panel, and a display device, and the pixel compensation circuit includes: a threshold compensation module, a storage module, a light-emission control module, a driver transistor, and a light-emitting diode, where the threshold compensation module is configured to provide a control electrode of the driver transistor with voltage of a data signal terminal, and threshold compensation voltage in a data writing stage; the storage module is configured to store the voltage of the control electrode of the driver transistor in the data writing stage and a light-emission stage; and the light-emission control module is configured to connect a second electrode of the driver transistor with the light-emitting diode in the light-emission stage to drive the light-emitting diode connected with the driver transistor to emit light.
